To all whom it may concern.'

Be it known that I, FRANK P. Mins, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating and Ventilating Systems, of which the following is a specification.

My invention relates to improvements in heating and Ventilating systems.

One of the objects of my invention is to provide in a system of the character described a means for concentrating the heat from a source of heat in a chamber and forcibly removing the heated air therefrom and conveying same to the area to be heated and forcibly replacing the air so heated within said chamber with air of lower temperature, thereby causing a continuous stream of air to pass through said heated chamber.

@ther and further objects of my invention will become apparent to those skilled in the art from the description taken in conjunction with the drawings, wherein-- Figure 1 is a vertical central section of an apparatus for carrying my invention into effect; and Fig. 2 is a fragmentary similar view taken at ninety degrees therefrom.

In both views the same reference characters indicate similar parts.

In the embodiment illustrated, I provide preferably three chambers, one within the other.

5 indicates the smallest interior casing inclosing a fan chamber, 5. The fire chamber, 6, is inclosed by the casing, 6. The casings 5 and 6 are made preferably of cast iron to withstand high temperatures, such as stoves and furnaces are subject to receiving. jacket, 7, may be of galvanized iron or masonry, such as brickwork or the like, and surrounds the hot air chamber 7. An air intake, 7a, is controlled by a damper, 7", to admit air into the hot air chamber, 7. It will be observed that the chambers, 5 and 7, communicate through the ducts, 8, of which there are shown to be four.

The fan casing may be made integral with the casing 6, as shown, or they may be made separately and secured together in any suitable manner. There is an opening 9 in the fan casing around the fan shaft, known in the art as the eye of the fan through which air is drawn into the fan casing by operat-ion of the fan. The fan 10, in the casing 5,

ing 6 is provided with a lire grate, 18, sutiiciently high from its bottom part to afford an ash chamber 19, and the proper distance from the fan chamber to promote good combustion.

Openings, 20-21, firing and removing apertures are each provided with a proper door, not shown in the drawings. A smoke pipe, 22, is connected to the fire chamber, 6, for the escape of the products of combustion, and for producing' the necessary draft for good combustion. rIhe draft may be modilied by use of the damper, 23. The hot air pipes, 24 and 25, of which there may be any desirable number to convey the heat to the several respective areas to be heated, are connected to the hot air jacket, 7, similarly to the ordinary furnace. The source of heat is shown 'in the drawings to be a coal fire, 26, or the like, but it is manifest that gas, oil, or other means may be used to heat the confines of the fan chamber when desired. llhe fan casing 5 is provided with a series of outwardly-projecting ribs, 27, designed to increase the exterior Asurface of such casing for more rapidly absorbing the heat from the fire. This is a refinement that need not necessarily be employed.

The operation of my system is as follows: A fire is kindled in the lire' chamber, as usual in ordinary furnaces. The heat from the fire is absorbed by the casings 5 and 6 and the confined air within these chambers will rise and pass out of the hot air pipes 2A and 25 to the area to be heated. The damper 7b may be opened to admit relatively cold air through the apertures 7 a into the hot air chamber to replace that which has been heated and passed out through the hot air pipes. When the fan is not running, cold air will pass into the fan chamber through the pipe 15. When it is desirable to increase the capacity of the system the fan is rotated, the hot air therefrom and the hot air from the chamber 7 is forcibly directed through the hot air pipes, 24-25. When the hot air is driven by the fan out of the fan casing through the pipes 8, cold air is taken in through the pipe 16. The cold airpassing around the bearings, l2, and 13, keep them sufficiently cool as to permit of practical operation of the fan at all times. If desirable, lroller bearings may be substituted for those shown.

My system of heating and Ventilating provides a means for increasing the efficiency,

capacity, and effectiveness of a heating plant, by taking the heat immediately from the fire and forcibly driving it to the area to be heated. It has further advantage of varying the capacity of the device by varying thev speed of the fan and intensity of the heat supplied, either or both, to meet the temperature requirements. Furthermore, the system may be used to supply and distribute fresh cool air from a suitable source ink the various rooms, by the use of the fan, as in the Warmer seasons when it is not desirable to heat the air before distributing it.

In situations Where the air is not to be distributed to remote, separate areas, but is to be used near the apparatus, the outer casing, 7, and the distributing pipes 24 and 25, be-

come unnecessary, and casings, 5 and G, only may be employed and the system so used.

Having thus described an embodiment my invention, what I claim is: A An air heating apparatus comprising a casing inclosing a combustion chamber, and a surrounding jacket spaced apart therefrom .to provide an air heating chamber With distributing pipes leading therefrom, a fan casing Within the combustion chamber containing a chamber inclosing a fan and having air outlets through said combustion chamber into said air heating chamber, an air intake pipe passing through said air heating chamber, and said combustion chamber and providing an air intake opening for said fan chamber, and a shaft for rotating said fan having bearings in said pipe cooled by the incoming air and provided With driving means on its outer end.

In testimony whereof I hereunto set my hand in the presence of two Witnesses.
